Snout rather short, obtuse, much depressed, with deeply concave 
loreal region, sharp canthus rostralis, and convex upper. labials. 
Lower eyelid with a very large transparent disk. Nostril on the 
canthus rostralis, just above the suture between the rostral and 
the first labial; a postnasal; anterior loreal largely in contact 
with the first labial; supranasals in contact behind the rostral ; 
frontonasal as long as broad, or a little broader than long, usually 
in contact with the frontal; latter as long as the frontoparietals 
and interparietal together, in contact with the second and third 
(rarely also the first) supraoculars ; four supraoculars, second largest ; 
five supraciliaries, second largest; frontoparietals distinct, as large 
as or a little smaller than the interparietal; parietals entirely sepa- 
rated or forming a very short suture behind the interparietal; a 
pair of nuchals; subocular much narrowed inferiorly, bordering the 
lip between the fourth and fifth, or fifth and sixth upper labials.

three or four long lanceolate lobules anteriorly. Dorsal, nuchal, 
and lateral scales strongly tricarinate; 30 to 34 scales round the 
middle of the body, subequal. The hind limb reaches the axilla or 
the shoulder. Toes long; scales on the soles sharply keeled; sub- 
digital lamellae sharply unicarinate. Tail once and a half to once
